Configuring vSphere HA Cluster Settings
When you create a vSphere HA cluster or configure an existing cluster, you must configure settings that
determine how the feature works.
In the vSphere Web Client, you can configure following the vSphere HA settings:
Failure conditions and
VM response
Provide settings here for VM restart priority, Host isolation response, VM
monitoring sensitivity, and VM Component Protection.
Admission Control
Enable or disable admission control for the vSphere HA cluster and choose a
policy for how it is enforced.
Datastore for
Heartbeating
Specify preferences for the datastores that vSphere HA uses for datastore
heartbeating.
Advanced Options
Customize vSphere HA behavior by setting advanced options.
NOTE You can check the status of vSphere HA configuration tasks on each of the hosts in the Tasks console
of the vSphere Web Client.
Configure Virtual Machine Responses
The Failure conditions and VM response page allows you to choose settings that determine how vSphere
HA responds to host failures and isolations. These settings include the VM restart priority, host isolation
response, settings for VM Component Protection, and VM monitoring sensitivity.
Virtual Machine Response page is editable only if you enabled vSphere HA.
Procedure
1 In the vSphere Web Client, browse to the vSphere HA cluster.
2 Click the Manage tab and click Settings.
3 Under Settings, select vSphere HA and click Edit.
4 Expand Failure Conditions and VM Response to display the configuration options.
Option Description
VM restart priority
The restart priority determines the order in which virtual machines are
restarted when the host fails. Higher priority virtual machines are started
first. This priority applies only on a per-host basis. If multiple hosts fail, all
virtual machines are migrated from the first host in order of priority, then
all virtual machines from the second host in order of priority, and so on.
Response for Host Isolation
The host isolation response determines what happens when a host in a
vSphere HA cluster loses its console network connection, but continues
running.
